Manuscript Summary: This manuscript contains an anonymous Hebrew paraphrase of the first five books of Averroes' (Abu al Walid Muhammed Ibn Rushd, c.1126-1198) Commentaire Moyen (middle commentary) on the Organon attributed to Aristotle. From the 13th century on, Hebrew paraphrases and compilations of certain books of the Organon were written by intellectual Jews from Provence, such as Jacob Anatolio Abba Mari (ca. 1194-1256); more than fifty manuscripts of this work of his have survived. The anonymous paraphrase found in the Bibliothèque de Genève’s Ms. heb.12 is part of the same series. (iss)
